A wheat bran extract in a hair care blend

ABSTRACT

Suggested is a hair care blend, comprising: (a) at least one wheat bran extract, and (b1) at least carboxylic acid alkyl ester and/or (b2) at least one diol.

FIELD OF INVENTION

The present invention belongs to the area cosmetics and refers to new blends for strengthening and protecting human hair.

STATE OF THE ART

A German saying concludes that often a head of golden hair is more expensive than a bag of ducats. And in fact, until 2012 the global market for hair care products is expected to reach a volume of 94 billion dollars. Particular female customers expect a constant development of modern hair care products in terms of more volume, more shine, better combability and higher protection against environmental pollution and stress. A quote from Ivana Trump takes it to the point: “Gorgeous hair is a woman's best revenge”.

Taking into account the amazing growth perspective, cosmetic industry is constantly interested in new actives improving the performance of their shampoos, conditioners and all other products within the universe of hair care preparations. At the same time much R&D work is spent on already existing actives and preparation in order to find additives for synergistic improvement of their performance.

One of those well-established products are wheat bran extracts, particularly extracts of Triticum vulgare. These extracts are typically obtained by extraction of wheat bran by means of overcritical carbon dioxide. They provide moisture and provide softness and smooth feeling to human skin. The extracts are particular useful for making skin care products, but are also used for shampoos and treatment of scalp. However, while wheat bran extracts show interesting approaches for example with respect to hair combability, their overall performance leaves space for improvement.

Therefore, it has been the object of the present invention to develop new blends based on wheat bran extracts with improved performance, in particular with respect to combability, shine, luster, break extension, volume, shape retention and protection against environmental pollution and stress.

DESCRIPTION OF THE INVENTION

The object of the present invention is directed to a hair care blend, comprising:

-   (a) at least one wheat bran extract, and -   (b1) at least carboxylic acid alkyl ester and/or -   (b2) at least one diol.

Surprisingly, it has been observed that the blends according to the present invention fulfil the complex profile and in particular simultaneously

-   -   improve dry and wet combability     -   improve shine and luster     -   improve break extension     -   improve volume     -   improve shape retention, and     -   reduce damage         of human hair. Compared to the sole ingredients the blends show         an synergism (according to Kull's equation) of about 0.7.

Wheat Bran Extracts

Wheat bran means the broken coat of wheat. Wheat bran extracts are also called Triticum vulgare extracts (CAS 84012-44-2). They are obtainable for example by overcritical extraction of wheat bran using carbon dioxide as for example disclosed in EP 0623100 A1 (UNIVERSITY R&M).

According to the extraction conditions the extracts, which are rich in lipids, can be soluble or at least dispersible in oils or in water. A water soluble product may contain additional solvents such as for example ethylene glycol, propylene glycol or glycerol in amounts up to 25% b.w. For example, a water soluble product may contain about 30 to 35% of wheat bran extracts, about 15 to 25% b.w. propylene glycol and up to 100% b.w. water, optionally including small quantities of preservatives. An oil soluble product may contain oil bodies, such as long-chain unsaturated fatty acids or their esters. For example, an oil soluble product may contain 75 to 85% b.w. wheat bran extracts and 15 to 25% linoleic acid. Since the extracts are of plant origin, they may contain minor amounts of natural antioxidants. Preferred extracts are Biobranil® Oily and Biobranil® PGW (both SYMRISE AG).

Carboxylic Acid Esters

Typically carboxylic acid esters forming component (b1) represent alkyl esters of fatty acids. Preferably these esters follow general formula (I)

R¹COO—R²  (I)

in which R¹CO stands for a saturated or unsaturated, linear or branched acyl radical having 6 to 22 carbon atoms and R² stands for a linear or branched alkyl or alkenyl radical having 1 to 22 carbon atoms. More particularly, the blends according to the present invention comprise one or more carboxylic acid ester of formula (I) in which independently from each other

-   -   R¹CO stands for a saturated, linear acyl radical having 8 to 12         carbon atoms, and/or     -   R² stands for a linear alkyl radical having 12 to 18 carbon         atoms.

Suitable examples encompass esters based on the following carboxylic acids: capronic acid, caprylic acid, nonanoic acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linoleic acid, arachidonic acid, gadoleic acid, behenic acid, erucic acid and their natural or technical mixtures and fractions such as coconut oil acid, palm oil acid, tallow fatty acid, olive oil acid or sunflower oil acid.

The alcohol component of said esters can be derived from methanol, ethanol, propanol, isopropyl alcohol, one of the isomeric butanols, pentanol, hexanol, heptanol, octanol, 2-ethylhexanol, nonanol, decanol, undecanol, dodecanol, tri(iso)decanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, oleyl alcohol, linolyl alcohol, linolenyl alcohol, gadoleyl alcohol, erucyl alcohol, behenyl alcohol and their natural or technical mixtures and fractions.

Suitable anti-microbial agents are, in principle, all substances effective against Gram-positive bacteria, such as, for example, 4- hydroxybenzoic acid and its salts and esters, N-(4-chlorophenyl)-N′-(3,4- dichlorophenyl)urea, 2,4,4′-trichloro-2′-hydroxy-diphenyl ether (triclosan), 4-chloro-3,5-dimethyl-phenol, 2,2′-methylenebis(6-bromo-4- chlorophenol), 3-methyl-4-(1-methylethyl)phenol, 2-benzyl-4-chloro-phenol, 3-(4-chlorophenoxy)-1,2-propanediol, 3-iodo-2-propynyl butylcarbamate, chlorhexidine, 3,4,4′-trichlorocarbanilide (TTC), antibacterial fragrances, thymol, thyme oil, eugenol, oil of cloves, menthol, mint oil, farnesol, phenoxyethanol, glycerol monocaprate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylic acid N-alkylamides, such as, for example, n-octylsalicylamide or n-decylsalicylamide.

Enzyme Inhibitors

Suitable enzyme inhibitors are, for example, esterase inhibitors. These are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (Hydagen CAT). The substances inhibit enzyme activity, thereby reducing the formation of odour. Other substances which are suitable esterase inhibitors are sterol sulfates or phosphates, such as, for example, lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, such as, for example, glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and esters thereof, such as, for example, citric acid, malic acid, tartaric acid or diethyl tartrate, and zinc glycinate.

Odour Absorbers and Antiperspirant Active Agents

Suitable odour absorbers are substances which are able to absorb and largely retain odour-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that perfumes must remain unimpaired in this process. Odour absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odour-neutral fragrances which are known to the person skilled in the art as “fixatives”, such as, for example, extracts of labdanum or styrax or certain a bietic acid derivatives. The odour masking agents are fragrances or perfume oils, which, in addition to their function as odour masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal products, such as, for example, civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linaool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Essential oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniperberry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures.

Suitable astringent antiperspirant active ingredients are primarily salts of aluminium, zirconium or of zinc. Such suitable antihydrotic active ingredients are, for example, aluminium chloride, aluminium chlorohydrate, aluminium dichlorohydrate, aluminium sesquichlorohydrate and complex compounds thereof, e.g. with 1,2-propylene glycol, aluminium hydroxyallantoinate, aluminium chloride tartrate, aluminium zirconium trichlorohydrate, aluminium zirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate and complex compounds thereof, e.g. with amino acids, such as glycine.

-   (i) providing a mixture of claim 1, and -   (ii) incorporating said mixture into a hair care or personal care     composition, and -   (iii) bringing said hair care or personal care composition into     contact with human hair.

Finally, the invention also encompasses the use of said blends for improving and strengthening human hair.

The preferred embodiments, particularly combinations of compounds and their ratios as explained in the earlier sections, shall also refer to the method and the use claimed above. Therefore, repeating these statements is not necessary.

In the following, the invention is illustrated in more detail by various working examples, without limiting the invention to these specific embodiments.

EXAMPLES Examples 1 and 2, Comparative Examples C1 to C4 Hair Combability

Hair combability test measures the force required for standard comb to pass through a hair tress. The parameter measured is:

-   -   Total work: the total energy required during the whole combing         process (Joules)     -   Peak of Force: the maximum force registered during the combing         process (gmf)

Since the hair surface characteristics are dependent on the cuticle/comb interaction, hair in wet or dry situations can change the values in the measurements. Caucasian bleached tresses were treated 5 times with the samples. Test in wet condition was performed. The tresses were dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation in dry condition. Comparisons among the samples were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner. The results are compiled in Table 1. Examples 1 and 2 are according to the invention, examples C1 to C4 serve for comparison. The values express the percentage of improvement when compared to placebo.

Examples 7 and 8, Comparative Examples C13 to C16 Volume/Frizz Control Assessment

Volume is the gain of body in a hair tress due to its humidity exposure or mechanical actions such as combing or friction of fibers. Frizz is the bristling of some fibers of hair that get apart from the tress body (fly-away effect). Anti-frizz/volume test measures the variation in the shape of the tress after exposure to a high humidity environment, for a controlled period of time. The parameter measured is:

-   -   Number of Pixels in the Image

Afro virgin tresses were treated 5 times with the samples and dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation. They were straightened with a flat iron. Images at initial time were captured. Tresses were left for 4 h at 70% relative humidity environment. Images at final time were captured. Comparisons between initial and final time were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner.

Examples 9 and 10, Comparative Examples C17 to C20 Fluorescence Microscopy

Rhodamine B is cationic and presents affinity with damaged regions of the hair. Tresses are treated and then soaked in solution with Rhodamine B. It reacts with the negative sites of damaged hair. A fluorescent complex is formed in the hair fiber and can be detected when exposed to a fluorescence microscope. After capturing images in the microscope, the intensity of luminance in the images is quantified by image analysis.

The parameter measured is luminance intensity as expression of damage. A treatment that generates images less fluorescents expresses the effect of penetration of the formulation. Caucasian bleached tresses were treated 5 times with the samples. The tresses were dried at controlled temperature and humidity (22° C.+/−2° C. and 55% RH) overnight before evaluation. Microscopic images were made and then analyzed to calculate the luminance intensity. Comparisons between treated and untreated hair were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner. Pure ingredients were incorporated at half of its respective blend, i.e.: SymMollient S=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Biobranil Oily=0.05% b.w. in shampoo and 0.25% b.w. in conditioner; Hydrolite 5=0.5% b.w. in shampoo and 0.5% b.w. in conditioner; and finally Biobranil PGW=0.5% b.w. in shampoo and 0.5% b.w. in conditioner. The results are compiled in Table 5. Examples 9 and 10 are according to the invention, examples C17 to C20 serve for comparison. The values express the percentage of improvement when compared to untreated hair.

The examples and comparison examples clearly indicate that adding certain diols and/or esters reduces damage of human hair in different consumer formulations in synergistic manner.

Examples 11 and 12, Comparative Examples C21 to C24 Swelling Test

Through diameter measurements, it is possible to determine the level of swelling of a fiber of hair over time. The laser measures the variation in the fiber diameter as it absorbs water over a pre-determined time. According to the fiber condition or the film covering its surface, the level of swelling may change. The more damaged the hair, more hydrophilic it is and, consequently, more swelling is noticed since most of the hair damages take the lipids, ceramides and other hydrophobic substances away from the hair. The parameter measured is:

-   -   % of swelling as % of the fiber diameter variation.

Caucasian bleached tresses were treated 5 times with the samples. The tresses were dried at controlled temperature and humidity (22°C.+/−2° C. and 55% RH) overnight before evaluation. Comparisons among the samples were made. Statistical analysis was performed with analysis of variance, followed by post-test of Tukey, considering 95% of confidence interval. The blends were incorporated at specific concentrations in shampoo and conditioner formulations: example 1=0.1% b.w. in shampoo and 0.5% b.w. in conditioner; example 2=1.0% b.w. in shampoo and 1.0% b.w. in conditioner.
